ABRADING-DISK FOR GLASS- GRINDING MACHINES.

Specification of Letters Patent.

Patented Feb. 9, 1909.

Application filed May 2a, 1906. Serial No; 319,178.

To all whom it may concern:

Be it known that I, ISIDORE RAMBOUX, a

' subject of the; King of Belgium, and resident of Erquelinnes, Belgium,have invented new and useful Improvements in'Abradin Disks forGlass-Grinding Machines, of whic the following is a specification.

This invention relates to machines for grinding glass plates, marbleslabs and the ike, and more particularly to the abrading mechanismtherefor.

In the annexed drawing: Figure 1, is a sectional .vieW of a grinding andpolishing disk carrier constructed according to the present. invention.Fig. 2, is an under-- Fig. 3, illustrates increase of the amount of workdone as no the above stated material placing itself under the knobs orgrinding disks made of cast iron.

The cast iron plates of the marble slab grinding machines must equally.be provided with holes having the desired dimensions with a view ofascertaining the feed of the above stated materials. The buttons orgrinding disks of these plates may also be provided with holes. With aView of obtaining during the feeding operation of the above statedmaterials a great saving of the said materials and of work all the castiron abrading members, which may have a square, rectangular, oval,octagonal, circular or other shape, must be provided with holes. It willbe preferable to use circular abrading members, which may be of large,medium or small size. l

On the grinding disk carrier a Wire lattice or sieve is provided inorder to cause the sand and the emery to fall in a convenient manner onthe platforms or tables and to preventthe fiints contained in the sandfrom passing through. Owin to this arrangement any breakage whic mightoccur during the grinding o eration owingto the presence of these intsis avoided. The water used for the'grinding operation could be caused tofall on the platforms or on the abrading member carrier when the sand isnot very dry. Y

The sand may be replaced by other materials such as metallic globulesand the like which are put on the platforms or tables or on the abradingmember carriers in the above described manner. These materials could berecovered by means of a tank ,or gutter secured by means of hinges tothe circumference of the platform. The said globules could be recoveredand used again as many times as judged convenient.

The dimensions of the holes may vary ac cording to the dimensions of theabrading carriers and the work to be performed.

With my abrading members no strong a plying pressure is needed andconsequent y combustible may be saved as the required motive power isless im ortant.

On the upper side of t e abrading member carrier and in front of each ofthe perforated abrading members funnels preferably made of sheet metalare arranged. These funnels will all be arranged in such a manner thatthe abradingmaterials will exactly fall directly into the holes of theabrading members. The wire lattice or sieve will be arranged above thesefunnels.

The whole will be made of cast iron, or of steel and the like and bearranged in such a manner that the abrading members and the rim may bewell secured in place.

The Figs. 1 and 2 of the annexed drawings show an abrading disk carrierconstructed according to this invention;

13 designates a bucket chain arranged at a suitable distance of theplatform.

14 is the Wire lattice arranged above the funnels 15.

Carried by the bottom member 17 is a cover-16 forming a space betweenthe to of the funnels l5 and the base 17. 17 is the ottom of thiscarrier and 18 are the abrading disks. The latter are provided each withthree lugs 19provided witlf two holes.

The

The abrading disks may be provided with holes as shown in Fig. 3.

According to the feed which the 1T1Ln11f80- turer desires to obtain amore or less large number of cast iron abrading members may be arrangedon the ebreding member carrier, or holes may be provided between thefunnels.

Having now fully described my sui d iuvention, what I claim and desireto secure by Letters Patent is:

1. In it grinding and polishing machine the combination of or rotatingperforated carrier, a cover carried thcrebj forming a compartment,funnels attending through the cover and communicating with certain ofthe per forotions of the carrier and. perforated disks carried by theunder surface of the nrrier, the perforations of the disk registeringwith the perforations of the carrier.

2. in. it grinding and polishing nuiehine,

I the combination of it rotating perforated carrier with compartmentsthereovcr, funnels discharging into perforations of the carrier, anddisks applied to the under surface of the carrier and having aperturesalining with the perforations in the carrier.

in testimony whereof i. have hereunto set in hand in presence of twowitnesses.
